Sitting in the packed, hot, venue with your whole leg alongside a stranger’s, you start to think that maybe you have literally bought tickets for a threesome as a movie clip plays on stage introducing us to couple Sam (Chris Willoughby) and Kate (Gemma Rook) who are going through a rough patch in their marriage when they bump into Lucy (Skins, April Pearson). The aptly titled Threesome explores the couple’s relationship and if they should or shouldn’t go through with the act being seductively encouraged by Pearson.

The acting is good with a well picked cast seeing Willoughby as the stand out playing a fumbling guy waiting for both women to decide if they get on, snorting lines of coke and hamming up his lines. You can tell he really enjoys the part he is playing helped along by the script to deliver an earnest performance which can be hard to compete with, even as Pearson plays a saucy 3rd wheel to the couple encouraging them to talk dirty and get crazy. The set as well as props are simple and perfect for assisting the actors rather than distracting the audience unnecessarily. Dynamics between the actors is tense, believable and just sexy enough thanks in part to a great script.

The show is good until the end with a disappointing, yet predictable finish. Much more could have been done with the story and script leading to a somewhat disappointing finish in what is otherwise a great show featuring a controversial, risque subject. Threesome is an entertaining adventure with enticing, well acted characters and plot, however it feels flat at the end leaving audiences not quite satisfied.
